I am looking forward to letting my SIL machine a new set of rear rotors for
my TSM disc conversion. I would like to confirm my search findings. I found
one place where it is described as a 3.9 id.
Too big me thinks.
3.09 got a mention as well. Correct?
Thank you for your opinions!

Emery thanks
but i think i have all the info i need
i am unsure of when Bobby installed this system but i found this article in a google search
so i assume prior to 1998 http://www.henry-davis.com/GMC/Sandy/discbrake.htm
this system he put on has long changed
originally i believe bobby put on 4 eldroado calipers and discs connected
to a electric seat actuator mounted in front of the fuel tanks that was
controlled by a switch in the wall beside the drivers seat
when he passed the coach was sold to a guy called Chester
in indiana who replaced the calipers with standard 80mm calipers
we then purchased the coach from Chester and shipped to Australia.
here we had to have a working handbrake so i swapped out the rear discs
for a set of drums and installed an original handbrake lever to actuate the drums.
on our last trip one caliper dragged and scoured up the disc.
i have since measured all of the discs and they are below the wear limits
so i have ordered new eldorado discs from rock auto. i will machine these myself
using the discs currently on the coach and the document posted earlier for reference
i believe that i will need to enlarge the hub hole which will be different for the fronts compared to the back I
I also have a spare disc that came with the coach but it too is on the limit of wear at 1.170 inches
